摘    要:<正>我们的多点子代测定的研究从1976年开始,于1978年结束。本研究的结果表明:家系×地点的方差分量基值的高百分比率(10~20%),证实了杉木的GEI是非常显著的。 在本研究中根据遗传型的稳定性,多点子代测定被研究的家系可分为三种类型,即“速生稳定型”(占20~25%)、“变化型”(50~60%)、“慢生型”(20~25%)。 我们的研究证实:杉木家系当半同胞子代在三个不同地区测定时(具有共同遗传对照),其家系均值的稳定性值是0.691;然而,当在两个不同地区测定时,共家系均值的稳定性在0.533以上。最后,当全同胞子代在两个不同地区测定时,其家系均值稳定性值接近0.52。


STUDIES ON THE GENOTYPE x ENVIRONMENT INTERACTION AND GENOTYPIC STABILITY OF CHINESE FIR II Analysis of the Multiplantation Progeny Test
Abstract:Our study on the multiplantation progeny test started in 1976 and was completed in 1978. Results of this study show the high proportional contribution of variance components of the family U3 site interaction (10~20%), which indicates that the GEI in Chinese fir was very significant.According to their genotypic stabilities observed in this study, the families investigated in the multiplantation progeny test can be divided into three classes, i. e, "fast growing stability" (20~25%), "variable" (50~60%) and "slow growing" (20~25%).Our investigation indicated that in the halt-sib progeny tests carried out in three different locations with a common genetic check, family mean repeatability for Chinese fir was found to be 0.691. However, when progeny tests were carried out in two different locations family mean repeatability turned up to be about 0.533. Finally, when full-sib progeny tests were carried out in two different locations results showed a family mean repeatability around 0.52.
